1. A system useful for remotely controlling an alternating current across at least two electrical terminals, the system comprising:
a transmitting unit including
an alternating current detector configured to be electrically connected to a source of alternating current, the alternating current detector including a signal output;a controller having
an external interrupt in communication with the signal output of the alternating current detector, anda data output,wherein the controller is configured to determine a duty cycle of a signal from said signal output of the alternating current detector and generate a signal representative thereof to said data output, andan RF transmitter in communication with the controller data output, the RF transmitter being configured to wirelessly transmit data representative of the signal representative of the duty cycle; and a receiving unit including
an electrical connector inlet configured to be connected to a wall outlet of alternating current,an alternating current control in electrical communication with said electrical connector inlet and including a signal inlet and at least one pole of a controlled alternating current outlet,a controller having a control signal output in signal communication with the alternating current control signal inlet, the controller including a data inlet;an RF receiver having an outlet in signal communication with the controller data inlet, the RF receiver configured to receive data from the RF transmitter representative of duty cycle,wherein the controller is configured to generate a signal representative of duty cycle data received from the RF receiver, and to output said signal to said controller control signal output, andwherein the alternating current control is configured to change the duty cycle of alternating current across said electrical connector outlet based on the signal at said signal inlet from said controller. |
